During power-up, initial application of nonzero voltages to any
of the input pins must be delayed until the supply voltage ramps
up to at least the highest maximum operational input voltage.
During power-down, the voltage at any input pin must reach

Verification of the Maximum Operating Junction
Temperature
In order to verify the system thermal design for compliance
with the maximum operating junction temperature specifica-
tion, temperature measurements T CASE and T PCB are required at

zero during a period not exceeding the hold-up time of the
power supply.
Failure to comply with the Absolute Maximum Ratings may
result in functional failure or damage to the internal ESD
diodes.
Damaged ESD diodes may cause temporary parametric failures,
which may result in image artifacts. Damaged ESD diodes
cannot provide full ESD protection, thus reducing reliability.

LCD capacitance = 150 pF).
Although the case and PCB temperatures are highly dependent
on the PCB design, their measured values are expected to be
similar at approximately 40°C above the ambient (on a typical
PCB with a minimal airflow whose thermal design follows the
recommendations described in this note). The junction temper-
ature then calculates to approximately 10°C above the case and
PCB temperatures. At a 70°C ambient temperature, the junction
temperature is expected to be at approximately 120°C.
The AD8383 has a relatively small thermal mass. In order to

VBIAS Generation—V1, V2 Input Pin Functionality
In order to avoid image flicker, a bias voltage of approximately
1 V minimum must be maintained across the pixels of HTPS
LCDs. The AD8383 provides two methods of maintaining this
bias voltage.
Internal Bias Voltage Generation
Standard systems that internally generate the bias voltage
reserve the upper-most code range for the bias voltage and use
the remaining code range to encode the video for gamma
correction.

measuring device, a small-gauge thermocouple or a thermal
probe with a very small thermal mass is required for the mea-
